Can I activate a crew member, then ready her (with a special ability), then activate her again in the same turn?

For example, Riker has diplomacy 4. Can I get diplomacy 8 this way during a single interaction?

I do not see anything in the rules to disallow this, but it seems weird that you cannot use a crewmember twice in combat, but you can use them twice in a single interaction. (Ready abilities are belong to the "repair/heal" type which cannot be played during combat, but can be played during an interaction, correct?)
